If you are a fan of big guns, the 20mm is impossible to beat.

The monstrous 20mm Lahti L39 anti-tank rifle is what dream guns are made of for us recoil junkies. This anti-tank rifle is certainly not for the faint of heart.

Ian from Forgotten Weapons shows us a weapon that was feared in the beginning of World War II and continues to be a huge bullet-thrower. The 20mm Lahti L39 anti-tank rifle semi-automatic fire also allowed 10 rounds ready for quick fire. Originally well suited against the lighter armor of tanks at the time, this long distance delivery system can still get the job done on light and medium targets.

It certainly would be a bad day to be targeted by such a beastly weapon at any range. That indeed is one very incredible Forgotten Weapon.
